Thermal control fluid pipeline,as an important part of thermal control system,provides appropriate temperature guarantee for the normal operation of spacecraft systems.Focus on the technical difficulty and complex external design constraints on developing thermal control fluid pipeline in spacecraft,the paper analyses the characteristics and difficult points,then chooses a method which is more suitable for spacecraft thermal control fluid piping design based on“pipe”module of Pro/E,considering the interface validation,overall planning,pipe line libraries and layout as a whole.The method can realize the simple optimization design of pipeline,facilitate the rapid change of design,effectively guarantee the processing quality,reduce the difficulty of final assembly design,and realize the rapid optimization iteration of the overall design of pipeline.The method has been applied to the piping design of thermal control fluid and other subsystems of spacecrafts,and it shows that it can shorten the design and assembly cycles effectively.
